In The Sherlock Society, how many acres make up The Lost City?

• A. Three
• B. Five
• C. Ten
• D. Twenty

Answer: (A)

The thing being tested is how large The Lost City is described to be within The Sherlock Society. The materials depict it as a compact, contained area—more like a small enclave than a sprawling region. That keeps the size limited to a small footprint, so the option representing the smallest acreage aligns with the canonical description. If the city were described as larger, it would imply a much bigger site than the text supports. So the interpretation that fits best is that The Lost City covers a small, tightly bounded area.
